The computer is having trouble recognizing the Dewesoft EtherCAT devices.
Description of the solution
Here are the steps that can resolve the problem:
Check if there is an Ethercat DAQ Filter driver installed on your computer like shown on the picture below.
If the driver is installed, make sure, the checkbox is checked in front of the driver.
If the driver is not installed, it can be downloaded from our web page.
If the driver is already installed and the devices are still not recognized, the Speed & Duplex of the network card needs to be adjusted manually.
- Go to network connections
- Right-click on the connection where the EtherCAT devices are connected
- Go to configure, advanced options, find Speed & Duplex, change the value to 100 Mbps Full Duplex
Uncheck "Disable EtherCAT interface".
If all those steps still don't allow detecting EtherCAT devices, you might check your Firewall settings . Disable it and reconnect the EtherCAT device.
Antivirus programs might also block the EtherCAT communication. Disable or uninstall your antivirus program and try to reconnect the EtherCAT device. Below is the list of known antivirus programs that usually blocks the EtherCAT communication.
